The arrangements in place for reporting events on nuclear licensed sites in the UK are well established. The information received by the Nuclear Installations Inspectorate (NII) from the licensee is distributed according to the significance of the event. In this instance relevant Government Departments were alerted through the normal reporting arrangements. NII had no formal discussions with DTI or BERR about the event, but maintained regular contact at official level. Throughout its investigations NII kept the Environment Agency informed of progress.
The Environment Agency (EA) had no formal discussions with DEFRA concerning the incident though at official level there was regular contact.
